+FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
-+
-+
+. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
-+
-+
+. Support for inline blob encoding. Blob values pass using the "SetAsString" method
-+
+   will now be encoded inline (i.e. as part of the parameter buffer) if they are
-+
+   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
-+
+   separate server interaction. This is intended as a performance optimisation.
-+
-+
+   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
-+
+   IAttachment interface functions:
-+
-+
+    function GetInlineBlobLimit: integer;
-+
+    procedure SetInlineBlobLimit(limit: integer);
-+
-+
+. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
-+
+   user as the functionality is embedded in the implementation of the IStatement
-+
+   interface. Three new functions are defined:
-+
-+
+    procedure AddToBatch;
-+
+    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
-+
+    procedure CancelBatch;
-+
+    function GetBatchCompletion: IBatchCompletion;
-+
+    function GetBatchRowLimit: integer;
-+
+    procedure SetBatchRowLimit(aLimit: integer);
-+
-+
+   Also
-+
-+
+    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
-+
+    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
-+
-+
+   For more information see the User Guide.
-+
-+
+. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
-+
+   provided with the EIBInterBaseError now include all three parts.
-+
-+
+. Firebird.pas and include files updated to Firebird 4.0.0
-+
-+
+. New IStatement method: function GetSQLStatementTypeName: AnsiString;
-+
+   Returns SQL Statement type as a text string;
-+
-+
+. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
-+
+   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
-+
-+
+FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
-+
-+
+. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
-+
+   typo in FB30Statement.pas that caused an unknown parameter error.
-+
-+
+FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
-+
-+
+. Imported (Firebird) constants updated for Firebird 4.
-+
-+
+. Firebird.pas from Firebird 4 integrated into source code tree.
-+
-+
+. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
-+
-+
+. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
-+
-+
+. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
-+
+   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
-+
+   interface provides a single method "function GetIMasterIntf: IMaster". This provides
-+
+   type safe access to the Firebird IMaster interface and avoids the need to turn
-+
+   off object checks when coercing "function GetIMaster: TObject" to IMaster.
-+
-+
+. New IFirebirdAPI Calls:
-+
+    function HasLocalTZDB: boolean;
-+
+    function HasTimeZoneSupport: boolean;
-+
+    function HasExtendedTZSupport: boolean;
-+
+    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
-+
+    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
-+
-+
+. New IAttachment Calls:
-+
+    function HasDecFloatSupport: boolean;
-+
+    function GetTimeZoneServices: ITimeZoneServices;
-+
+    function HasTimeZoneSupport: boolean;
-+
-+
+. New Interface ITimeZoneServices.
-+
-+
+. New ISQLData API Calls:
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

-+
+    function GetAsUTCDateTime: TDateTime;
-+
+    function GetAsBCD: tBCD;
-+
-+
+. New ISQLParam API Calls
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
-+

-+
+    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
-+
+    function GetAsUTCDateTime: TDateTime;
-+
+    function GetAsBCD: tBCD;
-+

-+
+    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
-+
+    procedure SetAsBcd(aValue: tBCD);
-+
-+
+. New IArray API Calls
-+
+    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
-+
+    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
-+
+    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
-+
+    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
-+
+    function GetAsUTCDateTime(index: array of integer): TDateTime;
-+
+    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
-+
+    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
-+
+    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
-+
+    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
-+
-+
+. Utility functions in IBUtils
-+
+    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
-+
+              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
-+
+    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
-+
+    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
-+
+    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
-+
+    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
-+
+    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
-+
-+
+. IDPB, ITPB and ISPB: new interface method
-+
+      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
-+
+    This is used to add a parameter block item by the string equivalent of its
-+
+    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
-+
-+
+. IDPBItem/ITPBItem/ISPBItem: new interface method:
-+
+      function getParamTypeName: AnsiString;
-+
-+
+. fb_shutdown now called before unloading Firebird library. This can avoid a
-+
+     SIGEVENT error when a programme using the embeded server is unloaded.
-+
-+
+FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
-+
-+
+. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
-+
+   with a Firebrid 3 client library.
-+
-+
+. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
-+
+    If a client library path is not explicitly provided and the FIREBIRD environment
-+
+    variable is set then the directory given by this variable and any 'lib' subdirectory
-+
+    are searched for the Firebird client library. Only if none is found, is the default
-+
+    client library used.
-+
-+
+.  IUtil.FormatStatus now used to format error messages when using new API
-+
-+
+.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
-+
-+
+.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
-+
+    returned using GetAsString and the string codepage is UTF8, the string is truncated so
-+
+    that the byte length corresponds to the number of characters specified for the column.
-+
+    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
-+
+    correct behaviour but may affect some implementations that relied upon automatic
-+
+    trimming of trailing white space.
-+
-+
+.  New IFirebirdAPI Calls:
-+
+      function GetClientMajor: integer;
-+
+      function GetClientMinor: integer;
-+
-+
+.  IColumnMetaData and IArrayMetaData: new method
-+
+      function GetCharSetWidth: integer;
-+
-+
+FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
-+
-+
+. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
-+
+   case sensitive
-+
-+
+. Single line SQL comments starting with '--' are now recognised by SQL Parser.
-+
-+
+. New API Calls:
-+
+        IColumnMetaData.GetStatement
-+
+        IColumnMetaData.GetTransaction
-+
+        ISQLData.GetStrDataLength
-+
+        IResults.GetStatement
-+
+        IAttachment.OpenBlob (using Blob metadata)
-+
+        IAttachment.OpenArray (using array metadata)
-+
-+
+. FBMessages: removal of unused messages
-+
-+
+. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
-+
-+
+. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
-+
-+
+FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
-+
-+
+. Fix a problem with the SQL parameter parser that failed to recognise parameters
-+
+   where the second character of the parameter name is a numeric.
-+
-+
+. New method for IAttachment: procedure getFBVersion(version: TStrings);
-+
+   This returns the isc_version connection information as one or more lines.
-+
+   This is the same information as returned by isql with the -z option.
-+
-+
+. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
-+
+   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
-+
+   compiler option then the Firebird 3 API is no longer compiled in.
-+
-+
+. IColumnMetaData: new method.
-+
-+
+   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
-+
+                        dfDateTime,   {SQL DATETIME}
-+
+                        dfTime);
-+
-+
+   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
-+
-+
+   This returns the max. number of characters returned by the "AsString" method
-+
+   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
-+
-+
+. Additional argument for IAttachment.PrepareWithNamedParameters -
-+
+     CaseSensitiveParams: boolean = false
-+
-+
+   If this argument is set to true then SQL parameter names are assumed to be case
-+
+   sensitive and must be referenced (using ISQLParams.ByName) using the case
-+
+   sensitive name.
-+
-+
+. Bug fix: when setting a query parameter, it is now possible, when the parameter
-+
+   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
-+
+   .AsCurrency) and then subsequently to update the value to a non-numeric string
-+
+   using .AsString.
-+
-+
-+
-+
+FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
-+
-+
+. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
-+
-+
+. Restrict IsMultiThread check to Unix only for compatibility with
-+
+   https://bugs.freepascal.org/view.php?id=30535
-+
-+
+. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
-+
+   named parameters and is intended to avoid problems with (e.g.) Execute Block
-+
+   and processing internal parameters as statement parameters.
-+
-+
+. New interface IFirebirdLibrary provides access to the underlying firebird DLL
-+
+   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
-+
-+
+. New function added to IB.pas
-+
-+
+   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
-+
-+
+   This allows a Firebird Library to be loaded from an explicit path. use the
-+
+   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
-+
+   the library. It is possible to load Firebird libraries from different locations
-+
+   simultaneously, each with a distinct IFirebirdAPI.
-+
-+
+FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
-+
-+
+. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
-+
+   program compiled with -CR command line switch.
-+
-+
+. IServiceManager additions (informational):
-+
+    function getProtocol: TProtocol;
-+
+    function getPortNo: AnsiString;
-+
-+
+. IServiceManager improved error handling. Interfaces changed:
-+
+    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
-+
+    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
-+
+    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
-+
-+
+. IAttachment addition (informational)
-+
+    function GetSecurityDatabase: AnsiString;
-+
-+
+. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
-+
+   thus now returns accumulated stats for a select statement from opening a cursor
-+
+   up to the last fetch.
-+
-+
+. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
-+
+   the problem.
-+
-+
+. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
-+
+   replaces deprecated "comp" type.
-+
-+
+. Testsuite Test10 updated to include thread synchronisation for event reporting.
-+
-+
+. URL Connection Strings: inet4 and inet6 now recognised.
-+
-+
+. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
-+
-+
+. IAttachment.CharSetName2CharSetID is now performed case insensitive.
-+
-+
-+
+FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
-+
-+
+. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
-+
-+
+. IAttachment: add two new methods
-+
+     function HasDefaultCharSet: boolean;
-+
+     function GetDefaultCharSetID: integer;
-+
-+
+   These return, respectively, true if a connection default character set was
-+
+   specified and the character set id of the connection default character set.
-+
+   The DefaultCharSetID is cached when the connection is opened and hence does not
-+
+   require a database lookup.
-+
-+
+. Avoid exception when a text blob is a stored procedure parameter.
-+
-+
+. Update test suite to include a test for a stored proc returning a text blob.
-+
-+
+. IAttachment: add
-+
+      function GetRemoteProtocol: AnsiString;
-+
+      function GetODSMajorVersion: integer;
-+
+      function GetODSMinorVersion: integer;
-+
+      function GetAuthenticationMethod: AnsiString;
-+
-+
+   These results are cached when the connection is opened and hence do not
-+
+   require a database lookup.
-+
-+
+. IAttachment: add "function GetConnectString: AnsiString;" This returns the
-+
+   connect string used to create/connect to the database.
-+
-+
+. IAttachment: Create Database using SQL statement. The username and password
-+
+   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
-+
+   It is now possible to use IAttachment disconnect/connect to reconnect to
-+
+   a database for which the initial connection was established by a create
-+
+   database sql statement. Available in FPC only.
-+
-+
+. Update Test 1 to test 5, 6 and 7 above.
-+
-+
+. IBUtils code tidy up.
-+
-+
+. Parameter Block interfaces "find" method. As documented, this should have
-+
+   returned a nil interface when the item could not be found. Instead, an empty
-+
+   interface item was returned. "Find" now works as documented and will return
-+
+   a nil interface if the item cannot be found.
-+
-+
+. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
-+
-+
+. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
-+
+    requests with additional parameters. This is to enable support for fb_info_page_contents
-+
+    (return of page contents). Response to fb_info_page_contents returned as
-+
+    a string with code page CP_NONE.
-+
-+
+. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
-+
+    test suite updated.
-+
-+
+. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
-+
+    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
-+
-+
+. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
-+
+    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
-+
+    default connection port to be specified.
-+
-+
+FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
-+
-+
+. Fix issues with setting SQL Param values using SetAsString with Numeric types.
-+
+   Scale is no longer ignored.
-+
-+
+. Fix issues with setting SQL Param values using SetAsString with Date values
-+
+   not in locale format but which are recognised by Firebird. Date values that
-+
+   cannot be converted to a string using Pascal library are now passed through
-+
+   to Firebird as Text Strings.
-+
-+
+. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
-+
+   UTF8 and not UNICODE_FSS.
-+
-+
+. Charset ID problem. When using Firebird 3, with no default database character set
-+
+   and a column has a non-default collation specified, an incorrect character set
-+
+   id was being reported that could result in a 'division by zero' error when
-+
+   used by IBX. This has now been fixed.
-+
-+
+. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
-+
+   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
-+
+   the character sets supported can be updated on a per database basis. That is
-+
+   it is possible to add a (Firebird) user defined character set to a database.
-+
-+
+. Add RegisterCharSet to IAttachment. This is used to register a user defined character
-+
+   set supported by Firebird with the API.
-+
-+
+. Add missing isc_info_db_read_only to list of decoded Database Information items
-+
+   in FBOutputBlock.pas and update test suite to include this item.
-+
-+
+. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
-+
-+
+. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
-+
+   library or finding it by disk location, the PATH environment variable is now also set to
-+
+   include the FIREBIRD directory. This is to ensure that the correct dlls in the
-+
+   firebird client library dependencies are loaded.
-+
-+
+. Testsuite: Ensure consistent UTF-8 output on Windows console.
-+
-+
+. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
-+
-+
+. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
-+
-+
+. FB30Statement: A check has been added to ensure that all SQL Parameters
-+
+    have been given a value (including NULL). Previously, failing to set the
-+
+    value of an SQL Parameter could give rise to unpredictable results or
-+
+    an SQLDA error.
-+
-+
+. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
-+
-+
+. FBAttachment: Avoid string reference count error when processing an Ansistring
-+
+    parameter in an array of const passed to IAttachment.OpenCursor, etc.
-+
-+
+. FBAttachment: Allow for WideString and UnicodeString parameters in an array
-+
+    of const passed to IAttachment.OpenCursor, etc.
-+
